Microstructure and Properties Evaluation of Ductile Cast Iron Subjected to Hot Plastic Deformation and Ambient Temperature Compression [PDF]
Archives of Metallurgy and Materials, 2023 The as-cast microstructure of ductile cast iron (DI) was investigated using light microscopy (LM) and SEM techniques. Further the influence of hot plastic extrusion at 1000°C with plastic strain in the range of 20-60-80% on the transformation of the as ...

Hot Workability of 300M Steel Investigated by In Situ and Ex Situ Compression Tests
Metals, 2019 In this work, hot compression experiments of 300M steel were performed at 900−1150 °C and 0.01−10 s−1. The relation of flow stress and microstructure evolution was analyzed. The intriguing finding was that at a lower strain rate (0.

In-Depth Comparison of an Industrially Extruded Powder and Ingot Al Alloys
Metals, 2020 An industrial press was used to consolidate compacted aluminum powder with a nominal diameter in the range of 1 µm. Direct and indirect hot-extrusion processes were used, and suitable process parameters were determined from heating conditions, ram speeds

Experimental study of locally loaded timber in compression perpendicular to the grain [PDF]
, 2011 Since the test method for compression strength perpendicular to the grain was changed from a partial area to a full area loading test, strength values for softwood in EN 338 were significantly reduced.

Hot Particle Drag in Compressible Gas [PDF]
Aerosol Science and Technology, 1990 This paper examines the drag force felt by relatively large (250 micron) MgF2 particles moving inside the exhaust of a magnesium-teflon flare burned at reduced pressure (0.02 atm). It is shown that the well-known Stokes formula for the drag on a spherical particle must be modified to take into account the MgF2 particles' elevated temperature with ...

Atomic structure of hot compressed borosilicate glasses [PDF]
Journal of the American Ceramic Society, 2020 Abstract Borosilicate glasses have been in widespread use for over a century; however, a detailed understanding of the structural response to densification is still lacking. In this work, two commercial borosilicate glasses, viz., SCHOTT N‐BK7 ® (N‐BK7) and Borofloat33

Deformation behavior of a new Ni-Co base superalloy GH4251 during hot compression
Materials Research Express, 2023 The deformation behavior of a new Ni-Co base superalloy GH4251 under hot compression tests within the deformation strain window of 0.36 to 1.2 was investigated in the temperature range of 1050 ∼ 1170 °C and strain rate range of 0.001 ∼ 1 s ^−1 . Based on

Mean field effects in hot compressed nuclear matter [PDF]
Physical Review C, 1988 We study effects of the mean field in hot compressed nuclear matter in the context of the Vlasov Uehling-Uhlenbeck theory. The expansion of a spherical distribution at different temperatures is studied along with collisions of Nb+Nb and Au+Au at lab energies from 50 to 1050 MeV/nucleon.
